Need Opinions for Gheenoe Mod.!!!

I want to do a total gheenoe makeover on my gheenoe. I am going to add decks to thel front and back and do many other little things that will really make it over the top. But I want to take out the middle section to make it easy to walk to the front of the boat. Some people say if I cut it out it will put the structure in jeporady and others don't think it will matter. I suggested even adding some sort of supports to the sides. I really need the help, please comment!!!!
